On consoles, The House of the Dead: Overkill took one of the most well-trodden premises imaginable – shooting zombies in first-person, on rails – and used it to create one of the most memorably over-the-top games of all time. Taking tropes from grindhouse horror movies and cranking them to ridiculous levels, HotD:O was gruesome, hectic, and – as its characters awkwardly shoehorned f-bombs into nearly every sentence – so deliberately crass that it was impossible to see it as anything other than a comedy. The iOS version, subtitled The Lost Reels, scales all that back considerably.
